USART Control and Status
Register C – UCSRC
2502K–AVR–10/06
(1)
TXB8 is the ninth data bit in the character to be transmitted when operating with serial
frames with nine data bits. Must be written before writing the low bits to UDR.
Note:
• Bit 7 – URSEL: Register Select
This bit selects between accessing the UCSRC or the UBRRH Register. It is read as
one when reading UCSRC. The URSEL must be one when writing the UCSRC.
• Bit 6 – UMSEL: USART Mode Select
This bit selects between asynchronous and synchronous mode of operation.

Read/Write
Initial Value
1. The UCSRC Register shares the same I/O location as the UBRRH Register. See the
UMSEL
“Accessing UBRRH/UCSRC Registers” on page 163 section which describes how to
access this register.
